Biometric identification system

1. A biometric identification system comprising: an interface for data input/output with an attached electronic device or data input/output by proximity wireless communication with the electronic device, biometric data detecting means for acquiring the biometric data from a living subject, a memory for storing identification use biometric data used for biometric identification in a secure state, and controlling means for comparing the biometric data acquired by the biometric data detecting means with the identification use biometric data stored in the memory for identification and for outputting a predetermined request or predetermined data to the electronic device via the interface on the condition that the controlling means detects a match between the biometric data and the identification use biometric data, the controlling means including a hash of the identification use biometric data into the predetermined request or predetermined data, and the controlling means not transmitting either an encrypted form of the identification use biometric data or an unencrypted form of the identification use biometric data to the electronic device.

2. The biometric identification system as set forth in claim 1 , wherein said interface receives as input a license meta data generation request including content identification data identifying content data and said content key data used for encryption of said content data, said memory stores the meta data key data, and said control means encrypts said content key data input via said interface by said meta data key data read out from said memory, generates license meta data including said encrypted content key data and said content identification data, and outputs this via said interface to said electronic device.

3. The biometric identification system as set forth in claim 1 , wherein said interface receives as input a license request including the license meta data including content key data encrypted by meta data key data and content identification data identifying the content data and said meta data key data encrypted by public key data of said biometric identification system, said memory stores the license key data, secret key data of said biometric identification system, and public key data of a biometric identification system at the destination of said content data, and said control means decrypts said meta data key data input via said interface by said secret key data read out from said memory, decrypts said content key data input via said interface by the meta data key data decrypted, then encrypts this by the public key data of the destination biometric identification system, generates license data including said encrypted content key data and content identification data, and outputs this via said interface to said electronic device.

4. The biometric identification system as set forth in claim 3 , wherein said interface receives as input said license request further including judgment data for judging if said destination meets predetermined conditions, and said control means generates said license data conditional on said judgment data meeting predetermined conditions.

5. The biometric identification system as set forth in claim 4 , wherein said interface receives as input said judgment data further including hash data of said identification use biometric data stored in a secure state in the biometric identification system corresponding to said destination, and said control means generates said license data further including said hash data.

6. The biometric identification system as set forth in claim 1 , wherein said interface receives as input license data including content key data encrypted by public key data of said biometric identification system and content identification data, and said memory stores secret key data of said biometric identification system, and said control means decrypts said content key data input from the interface using said secret key data read out from said memory and outputs it via said interface to said electronic device.

7. The biometric identification system as set forth in claim 6 , wherein said interface receives as input said license data further including predetermined hash data, and said control means generates hash data of said identification use biometric data read out from said memory, compares said generated hash data with said predetermined hash data input from said interface, and, conditional on succeeding in identification, outputs said decrypted content key data to said electronic device via said interface.

8. The biometric identification system as set forth in claim 2 , wherein said control means generates said license meta data further including identification data of biometric data certificate data proving legitimacy of said identification use biometric data.

9. A biometric identification system comprising: an interface configured to input and output data with an attached electronic device or data input/output by proximity wireless communication with the electronic device, a biometric data detecting circuit configured to acquire the biometric data from a living subject, a memory configured to store identification use biometric data used for biometric identification in a secure state, and a controlling circuit configured to compare the biometric data acquired by the biometric data detecting circuit with the identification use biometric data stored in the memory for identification and to output a predetermined request or predetermined data to the electronic device via the interface on the condition that the controlling circuit detects a match between the biometric data and the identification use biometric data, the controlling circuit including a hash of the identification use biometric data into the predetermined request or predetermined data, and the controlling circuit not transmitting either an encrypted form of the identification use biometric data or an unencrypted form of the identification use biometric data to the electronic device.

10. The biometric identification system as set forth in claim 9 , wherein said biometric data detecting circuit is configured to acquire fingerprint data from a living subject.

11. The biometric identification system as set forth in claim 9 , wherein said biometric data detecting circuit is configured to acquire vein pattern data from a living subject.

12. The biometric identification system as set forth in claim 9 , wherein said biometric data detecting circuit is configured to acquire retinal pattern data from a living subject.

13. The biometric identification system as set forth in claim 9 , wherein said biometric data detecting circuit is configured to acquire voiceprint pattern data from a living subject.
